CHARACTERS OF TRIBES AND GENERA, 181 
same genus with Drynaria and Phegopteris of this work. 
Under Grammites I comprehend all the simple linear- 
fronded forms having free veins and one row of sori 
on each side of the mid.rib, the sori being more or less 
oblong or linear or sometimes even punctiform, the single 
row being the chief distinction between it and Cienopteris. 
This latter genus, however, also contains a few single- 
fronded species, but they have a higher degree of develop- 
ment, the fronds being normally pinnatifid and each lacing 
having its mid-vein with soriforous venules on each side. 
Blume, in his *Flora Javanica," figures and describes 
no less than twelve species of Grammitis as natives of Java. 
Not having seen specimens of many of these, and the 
figures being much alike, I am quite unable to arrive at a 
satisfactory conclusion regarding them. Sir William 
Hooker also appears not very satisfied with many of them. 
It can only be by careful examination and comparing them 
one with another in a living state, either in their native 
country or brought together under cultivation, that the 
species can be determined, they are widely dispersed, 
being found in both hemispheres, the greater number 
are found in the Malayan Islands, and extending to 
Australia.
